Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) said that a man came and said: I filled my trough for my animals so that I could water them. A man's she-camel came and breached my trough, and all the water flowed away. I got up hastily and in anger killed the owner of the she-camel with a sword. Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) said: This is not intentional killing, and he ordered him to repent.
